SERVICE INFORMATIONPRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000001851385

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used alongwith a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certaintypes of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRSsystem uses the seat belt switches to determine the front air bag deployment, and may only deploy one frontair bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.Information necessary to service the system safely is included in the SRS and SB section of this Service Man-ual.WARNING:• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision which would result in air bag inflation, all maintenance must be performed byan authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personalinjury caused by unintentional activation of the system. For removal of Spiral Cable and Air BagModule, see the SRS section.

• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in thisService Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-ness connectors.

Precaution Necessary for Steering Wheel Rotation After Battery DisconnectINFOID:0000000001851386

NOTE:• This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI

VEHICLE IMMOBILIZER SYSTEM - NATS).• Remove and install all control units after disconnecting both battery cables with the ignition knob in the

″LOCK″ position.• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.

If DTC is detected, perform trouble diagnosis according to self-diagnostic results.For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lockmechanism is adopted on the key cylinder.For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock andsteering wheel rotation will become impossible.If steering wheel rotation is required when battery power is interrupted, follow the procedure below beforestarting the repair operation.

OPERATION PROCEDURE1. Connect both battery cables.

NOTE:Supply power using jumper cables if battery is discharged.

2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, thesteering lock will be released.

3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can berotated.

4. Perform the necessary repair operation.5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting

the battery cables. (At this time, the steering lock mechanism will engage.)6. Perform a self-diagnosis check of all control units using CONSULT-III.

Precaution for Steering System INFOID:0000000001851387

• In case of removing steering gear assembly, make the final tightening with grounded and unloaded vehiclecondition, and then check wheel alignment.

• Observe the following precautions when disassembling.

- Before disassembly, thoroughly clean the outside of the unit.- Disassembly should be done in a clean work area. It is important to prevent the internal parts from becoming

contaminated by dirt or other foreign matter.- For easier and proper assembly, place disassembled parts in order on a parts rack.- Use nylon cloth or paper towels to clean the parts; common shop rags can leave lint that might interfere with

their operation.- Do not reuse non-reusable parts.- Before assembling, apply the specified grease to the directed parts.

STEERING WHEEL

On-Vehicle Inspection and Service INFOID:0000000001851391

CHECKING CONDITION OF INSTALLATION• Check installation conditions of steering gear assembly, front suspension assembly, axle and steering col-

umn assembly.• Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial

direction.

• Check steering gear assembly mounting bolts and nuts for looseness. Refer to PS-14, "Removal and Instal-lation".

CHECKING STEERING WHEEL PLAY1. Turn steering wheel so that front wheels come to the straight-ahead position. Start engine and lightly turn

steering wheel to the left and right until front wheels start to move. Measure steering wheel movement onthe outer circumference.

2. When the measurement value is outside the standard value, check backlash for each joint of steering col-umn assembly and installation condition of steering gear assembly.

CHECKING NEUTRAL POSITION STEERING WHEELNOTE:Perform neutral position inspection after wheel alignment.1. Make sure that steering gear assembly, steering column assembly and steering wheel are installed in the

correct position.2. Set vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.

• Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments ifsteering wheel is not in the neutral position. Refer to PS-15, "Disassembly and Assembly".CAUTION:Check the wheel alignment after adjusting the inner socket. Refer to FSU-6, "Wheel AlignmentInspection"

CHECKING STEERING WHEEL TURNING FORCE1. Park vehicle on a level and dry surface, set parking brake.2. Start engine.3. Check steering wheel turning force when steering wheel has

been turned 360° from neutral position using suitable tool asshown.

4. If steering wheel turning force is out of the specification, removeintermediate shaft and steering knuckle, and then measure therotating torque of the pinion assembly. Refer to PS-15, "Disas-sembly and Assembly".

CHECKING FRONT WHEEL TURNING ANGLECheck the maximum inside and outside front wheel turning angle for right and left with the turning radiusgauges as per the following procedure.1. Check toe-in.

NOTE:Perform front wheel turning angle after the toe-in check.

Steering wheel axial end play : 0 mm (0 in)

Steering wheel play : 0 – 35 mm (0 – 1.38 in)

Steering wheel turning force

: Less than 36 N (3.7 kg-f, 8.2 lb-f)

SGIA1192J

PS-7

STEERING WHEEL
< SERVICE INFORMATION >2. Place front wheels on turning radius gauges and rear wheels on
stands.

3. With the engine at idle, turn steering wheel from full left stop tofull right stop and measure the turning angles.

• Measure rack stroke if angles are outside the specified value.

- Disassemble steering gear assembly to check the cause that rackstroke is outside of the standard.

• Steering angles are not adjustable. Check steering gear assembly,steering column assembly and front suspension components forwear or damage if any of the turning angles are different from thespecified value. Replace any of them, if any non-standard condi-tion exists.

Removal and Installation INFOID:0000000001851392

REMOVALNOTE:When reconnecting spiral cable, fix cable with a tape so that fixing case and rotating part keep aligned. Thiswill omit neutral position alignment procedure during spiral cable installation.1. Set vehicle to the straight-ahead position.2. Remove driver air bag module. Refer to SRS-30 .3. Remove steering wheel lock nut after steering is locked.4. Remove steering wheel using Tool.
